Abstract
The degradation process requires a photocatalyst, which is generally a semiconductor material. Photocatalyst natural zeolite-TiO2/ZnO is used in the degradation process of dyeing industry wastewater with visible light irradiation has been conducted. To know the characteristics of natural zeolite photocatalyst-TiO2/ZnO, such as specific surface area and amount of active sites, as well as the ability of natural zeolite-TiO2/ZnO for degradation of dyeing industrial wastewater based on pH, COD (Chemical Oxygen Demand), TSS (Total Suspended Solid), and the concentration of the dyes. The optimum characteristics of synthesized photocatalyst were obtained that the specific surface area resulted in (1:3) optimum mass ratio of 19.172 m2/g, and amount of active sites was 52.2384 x 1020 sites/g. The optimum conditions for degradation of natural zeolite-TiO2/ZnO photocatalyst occurred at 120 minutes with the photocatalyst mass of 2.0 g, the optimum of wastewater volume of 45 mL, and the COD value of 122 mg/L, 0 mg/L TSS, and pH of 5.92. The percentage of degradation of the dyeing industry wastewater at the optimum conditions was 97.08%. The synthesized photocatalyst can be used for dyeing industry wastewater degradation.
